Subject: [RFC PATCH] arm: dts: vexpress: Set chosen 'stdout-path'
Date: Fri, 24 Sep 2021 16:48:44 -0500	[thread overview]
Message-ID: <20210924214844.1890478-1-robh@kernel.org> (raw)

Using chosen 'stdout-path' is the preferred way to set the console, but
several Arm, Ltd. platforms don't set it. Set it to the 1st serial port.

RFC because I don't have any idea what the baud rate is for real boards. 
If anyone knows, please comment and I'll add it.
